The following best practices can solve most issues related to firewalls and anti-virus software. For specific information about your particular software settings, contact the software manufacturer.

Best practices for firewalls or anti-virus software

Keep your security software up to date. Many security software vendors provide updates that correct known issues and provide the latest defenses against new security threats.

If your firewall or anti-virus software has High, Medium, or Low security settings, use the Medium setting when your computer is connected to your network.

If you changed any firewall or anti-virus settings, try going back to the default setting.

If your software has a setting called Trusted zone, use this setting when your computer is connected to your network.

If your software has a Do not show alert messages setting, make sure it is not turned on. When you install the HP software and use the printer, you may see alert messages from your firewall or anti-virus software that give you options to Allow, Permit, or Unblock the printer software. You should allow any HP software that causes an alert. Also, if the alert has a Remember this action or Create a rule for this option, select it. This is how the firewall or anti-virus software learns what can be trusted on your network.

Do not have more than one firewall enabled at the same time on your computer. For example, do not enable the Windows firewall provided by the operating system and a third-party firewall at the same time. Having more than one firewall enabled at the same time will not make you computer any safer and may cause problems.

note:

If you were unable to install your HP printer successfully, you may need to disable startup services and/or your firewall temporarily. Windows allows many programs and processes to run immediately upon startup. These programs and your firewall may be preventing you from installing the HP software or getting the printer on the network. These directions explain how to disable these programs and processes during printer setup.
